Table Reformatting and Cleanup on AAI-Multi_BS_MIMO-REQ

Introduction
Current MAC control message table in 16m/D8 is not clear from a readability point of view. Therefore alternative
table format is suggested in this contribution, and the text changes are proposed for AAI-Multi_BS_MIMO-REQ
MAC control messages.
Proposed Text
Remedy 1:
In the P802.16m/D8, page 190, line 7, replace Table 719 with the following table:
-------------------------------------------------- Text Start
-----------------------------------------------------------------
Table 719—Parameters for AAI_Multi_BS_MIMO-REQ message
Field
multiBsMimoRequest
Size
(bit)
1
Value/Description
Condition
0b0: Single-BS precoding with Multi-BS
Coordination
0b1: Multi-BS Joint MIMO Processing
Single-BS precoding with
Multi-BS Coordination
If (multiBsMimoRequest == 0b0){
NIP value encoded as difference to NIP_th_1
when multiBsMimoRequest = 0b0. The value
shall be interpreted as unsigned 2bits with units of
0.5dB
nipValueForSingleBS
2
for (i=1; i<=numbs; i++){
tempBsid
4
0b00 : NIP_th_1 dB
0b01 : NIP_th_1+0.5 dB
0b10 : NIP_th_1+1.0 dB
0b11 : above NIP_th_1+1.5 dB
numbs is the number of base station which
exceeds threshold
Range: 1-8
This represents Temp_BSID. Temp_BSID is
broadcasted through AAI-DL_IM message
}
}
Multi-BS Joint MIMO
Processing
If (multiBsMimoRequest == 0b1){
bitmapForRequestedAdjABSs
8
nipValueForJoint
2
Each bit in this bitmap represents one ABS and
the i-th bit (i=1,…,8) represents the neighboring
ABS (listed in AAI-DL-IM message) with the i-th
strongest channel to the AMS. Please refer
16.5.1.4.
Sum NIP value encoded as difference to
NIP_th_2 when multiBsMimoRequest = 0b1. The
value shall be interpreted as unsigned 2bits with
units of 0.5dB

IEEE C802.16m-10/1216r2

0b01 : NIP_th_2+0.5 dB
0b10 : NIP_th_2+1.0 dB
